Description

Technical Field

[0001] The utility model relates to the technical field of road repair, in particular to a road crack repairing machine. Background Art

[0002] After a road has been in use for a period of time, it will gradually develop various damages, cracks and other defects, which are collectively referred to as pavement diseases. One of the reasons for the cracking and crazing of asphalt pavements is that there are soft and mud layers in the pavement structure, the granular layer is loose, and the water stability is poor. Under the action of load and rainwater infiltration, pumping occurs, cracking occurs, and thus pavement damage is caused. The second is the poor quality of asphalt and asphalt mixture, that is, the adhesion of the asphalt mixture is poor, or the asphalt has low ductility, resulting in poor crack resistance, coupled with the infiltration of water, causing pavement cracking, which in turn causes pavement damage. In order to ensure the normal passage of the road, the cracks in the road surface must be repaired in time.

[0003] In the authorized patent with application number CN202223567743.6, a road crack repair mechanism is disclosed, including a base, the upper end of the base is fixedly connected to a material box, the upper end of the base is fixedly connected to a feed pump, the pumping end of the feed pump is connected to the material box, a hand lever is provided on the base, the lower end of the hand lever is hinged to a mounting plate, and the lower end of the mounting plate is fixedly connected to a filling head. The road crack repair mechanism is provided with a dust suction component. When the vacuum cleaner is started and the filling head is working, the dust box absorbs the dust in the cracks through the dust suction hole. The absorbed dust enters the vacuum cleaner through the dust suction pipe and is then discharged into the collection box. The dust is filtered by the filter plate and retained in the collection box. With the cooperation of the handle and the slide seat, the collection box can be easily taken out, thereby realizing the integration of filling and dust suction, and avoiding the problem of loose adhesion between the filler and the crack during filling. However, in the above patent, when the repair mechanism does not need to repair the road, it is inconvenient to store the dust suction pipe and the feed pipe, which brings inconvenience to the use.
